METHOD or FORMING STACKS.

Application filed March 14, 1919.

T 0 all whom it may concern Be it known that I, lVINrmn) JAooBs, acitizen of the .United States, residing at Dodge City, in the countyofFord and tate of Kansas, have invented certain new and usefulImprovements in Methods of Forming Stacks; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and-use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

This invention relates to a method of forming stacks of grain as it isharvested. In carrying out my invention I initially form the stack in astack former which, in practice, may consist of a wagon having sides,bottom and ends which are so constructed that initially an invertedstack is formed, which, upon removal from the former, may, by impactwith ground, reverse its contour to present a finished stack.

In removing this stack, it may be initially compressed or baled so as toeliminate the liability of disintegration thereof as it is removed fromthe former.

The device is so constructed that it may be hitched to a tractor orassociated with a grain header so that the grain may be discharged fromthe header elevator into the stack former, and preferably tightly packedduring the process of forming the stack.

In the drawings,

Figure I is a vertical longitudinal sectional view through a stackformer constructed in accordance with my invention.

Fig. II is an end view of the stack, preparatory to being removed fromthe former.

Fig. III is an end view of the finished stack.

Fig. IV is a fragmentary perspective view of the rear end of the former.

Fig. V is a side elevational view of a stack former constructed inaccordance with my invention.

Fig. VI is a detail perspective view of the I rear axle support and oneof the radius rods, and

Fig. VII 1s a cross sectional View through the stack former.

Specification of Letters Patent.

Serial No. 282,632.

out my method, I will describe in detail an approved apparatus by meansof which the stack may be formed.

Referring now to the drawings by numerals of reference:

1 and 2 designate the side sills of a wagon body which constitutes thestack former, as will be presently explained. Extending lengthwise ofthe wagon, and positioned at its longitudinal center, below the sidesills 1 and 2, is a center sill 3 connected to the side sillsbytransverse floor sills i and 5. the floor sills 4 and 5 beingconnected to the center sill 8 by tie-plates 6, as best seen in Fig.VII, and the outer ends of the sills 4 and 5 are connected to the sidesills by tieplates 7 and 8. The floor sills 4 and 5 sup port theflooring 9 which, as shown, is concave; that is, the sides of the floordiverge a relatively wide angle toward the side sills, the purpose ofwhich will be apparent hereinafter.

Upstanding stakes orstandards 10 and 11 are carried by the side sillsand support the side walls which consist of strips 12 and 13 runninglongitudinally of the vehicle, there being end strips 14 at the frontthereof which are also connected to the end stakes 10 and 11.

15 is an axle beam carrying axle 16 on which are mounted front wheels,the beam 15 being connected to the front of the vehicle by the tie beam17 and braces 18.

At the rear of the vehicle are stub axles 19 and 20 which are connectedto the side sills 1 and 2 by suitable clips 21 and these axles extendthrough the diamond-shaped bracket plates 22 and 23, one of which isshown in detail in Fig. VIas being secured to one of the side sills bybolts '24 and to a standard or stake by a bolt 25. The plates 22 and 23extend below the side sills land 2 and are connected to a truss rod 26upon which the center sill 3 may rest, said truss rods and plates beingreinforced. by struts 27 and 28, as best seen in Fig. VII. The platesare also connected to radius rods. The rear standards 10 and 11 aresomewhat larger than the remaining ones and these are connected by across bar 29 to which, with the standards which it connects, are securedthe side bars 30 and 31 of a yoke frame formed by the bars 30 and 31 andthe cross bar 29. The yoke frame side bars 30 and 31 may consist ofangles bent at the lower end in the and have a loose end of sulilcientlon form of loops 32 (see Fig. VI) to embrace the stub axle so as tosupport the outer ends, the inner ends being supported by the yokes 21.The axles are further braced by the radius rods 33 which are fastened tothe side bars 30 and 31 and to the side rails l and 2, one of thesebeing shown in Fig. VI, therefore, the rear sills 34 and 35'may besecurely supported upon the axles 19 and 20.

To the rear end of the wagon or former are secured skids 36, there beingan appropriate number, as best seen in lfigsl and IV, and the rear endof the vehicle 15 normally closed by the swinging gates 37 and 38. 39 isa cable'or rope which constitutes a baling tie or compressor for thestack after it has been formed and which also assists in removing thestack by having its ends connected to a stake or anchor 4L0 which may beconveniently driven into the ground adjacent to the locationof thestack.

In practising the invention, the gates are closed with the skids 3Ofolded against them, the whole being s cured by the cross bar ell in thecleats 42. The grain, grass or other material to be stacked will then'bedeposited in the former either by hand or by a header, elevator, itgenerally being desirable to have an operator in the former to evenlydistribute and stomp the material as it is received so that it willstack to the best advantage. It is to be understood that it is desirableto lay a strong cable upon the center sill the entire length of former 1to partially encircle the stack after it is iormed so that the two looseends may be secured to the stake 39, as shown in Fig. l. Lifter thestack is formed, as shown in Jig. ll,

the free ends of; the cable may be secured to the stake 39, it beingunderstood, of

course, that the gates 37 and 38 have been opened and the skids 36 restupon the ground, as shown in Fig. IV. Power is .then applied to theformer so that it is moved lengthwise of the stack, leaving the stackanchored to the stake 39.

As the former leaves the stack, it will slide down the skids 36 and bedeposited upon the ground. As the convex portion of the stack strikesthe ground, the two upwardly curved sides will move down to rest uponthe ground and since the stack is thicker at its longitudinal centerthan at the edges, the contour of the stack will be reversed, as shownin Fig. 111 so that the top will have a curved water-shedding slopetravels so to cut a continuous s'wathon all four sides of the field, astack may be deposited or a number of stacks may be deposited, duringthe travel of the machine. The next time around, another stack will beformed adjacent to the one previously deposited so it is obvious that ina large held, the stacks may be deposited in multiples uniform distancesabout the field so that with my device the stacl s will'be automaticallypositioned. I

The exact form and proportion of the device may vary but [have found inactual practice that a vehicle in the following proportions admirablyserves the purpose'iir tended length, 20 feet; width, 9 feet; height, 9feet; skids, 5 feet in length.

In order to eliminate liability'of binding of the stack in the formerwhen it is desired to remove it, I generally construct the front endslightly narrower than the rear end so the initial. movement of thestack toward the rear end will relieve the pressure and consequently thefriction against the sides of the stack.

Having thus described my invention, what i (-laim as new therein, anddesire to secure by lietteraPatent is:

1. The method of constructing stacks which consists in collecting grainin a travcling former having a concave bottom whereby the stack will beformed with a conveX' base, temporarily binding the stack, withdrawingthe stack longitudinally from the former to a plane support to permitthe stack to hex so that the convexportion will be at the top, andremoving the binder.

2. The method of constructing stocks which consists in collecting grainin a traveling former having a concave bottom whereby the stack will beformed with a convex base, binding the stack, withdrawing the stacklongitudinally from the former to a plane support to permit the stack toflex so that the convex portion willbe at the top.

In testimony whereof I aflix my signature.
